Question

Are able to form hypothesis for normal force​

Answer 1

Answer:

The normal force arises from the electromagnetic force; specifically, the electrons in the book push against the electrons in the table. Since the electrons don't want to get any closer to each other, the book stays on top of the table. The normal force is closely related to the friction force.

Answer 2

Answer:

The word "normal" in normal force is not referring to ordinary or commonplace. The "normal" here refers to perpendicular. This is because the normal force, usually represented with F n F_n FnF, start subscript, n, end subscript or just N, is a force that is directed perpendicular to the two surfaces in contact.
